Application filed August 29, 1922. Serial No. 585,096.

To all whom it may concern:

Be it known that we, FREDRIK LJUNG- srnoiu, 'a subject of the King of Sweden, residing at Brevik, Lidingon, Sweden, and Ismon BRoBERc, a subject of the King of Sweden, residing at Tallhyddan, Skarsatra, Lidingon, Sweden, have invented a new and useful Locomotive Provided with Condensers, of which the following is a specification.

This invention relates to locomotives pro- .vided with condensers and in which the movement is transmitted from a steam engine to a driving wheel device by means of a toothed gearing. The invention consists chiefly in that the steam engine, the toothed gearing and the driving wheel device are loembodiment of .a spherically movable c011- cated on a common bogie.

In case the steam engine in this manner islocated on abogie and consequently movable in relation to the condenser, it has proved difiicult to conduct the waste steam of the steam engine to the condenser or to an accumulating liquid receptacle connected with the, same or any other condensing receptacle. A further objectof the invention consists in a movable steam connection between the steam engine, as for instance a steam turbine, and the condenser. Such a connection is preferably effected by the outlet of the steam engine, said outlet extending preferably into the condensing receptacle, being provided with a device connecting the outlet with the coupling of the condensing receptacle and yielding to all the movements 0 the bogie in relation to the receptacle. A further object of the invention consists in the steam outlet piping extending parallel or nearly parallel to the plane through the driving wheel shafts and into the receptacle to apoint situated right above or nearly right above the point of'rotation of the bogie relatively to the receptacle, the

turbine being preferably situated outside the end wall of the condensing receptacle and the steam outlet being situated in the-longie tudinal direction of the condenser.

The invention isillustrated in the'accompanying drawing in which Fig. 1 shows a locomotive consisting of two carriages and having the. driving machinery placed on a bogie pertaining to the condenser carriage. Fig; 2 illustrates an of rotation 17 of the bogie relatively to the pling device. Fig; 3 shows another embodiment of such a device.

Referring to Fig. 1, 1 designates the fore carriage supporting the steam boiler 2,the

coal bunker 3 and the drivers cab 4. The

rear carriage} supports the air cooled condenser 6,-the liquid receptacle 7 and the driving aggregate 8 resting on the bogie 9. In the embodiment shown the driving aggregate consists of the turbine 11, the.

toothed gearing 12 and the connecting rod device 13. The steam turbine 11 is positioned at the one end of the receptacle 7 outside the end wall 14 of the receptacle, the

steam outlet 15 of the turbine extending into the condensing receptacle7 and being surrounded byacasing 16 connected with the condensing receptacle 7 or integral with the same. The outlet pipe 15 is parallel or nearly parallel to a plane through the driving wheel shafts and is connected with the casing 16 approximately above the point receptacle by means of a revolvable coupling 18. In order that the steam shall exhaust. above the water contained in the liquid receptacle, the outlet pipe 15 is extended by a bent pipe 19 fixed to the condensing receptacleu By'the aid of this coupling between the turbine outlet 15 and the condensing receptacle 7 the turbine will be able to follow all the movements of the bogie 9 about the point of rotation17, which movements may be universal and caused on the one hand by the swinging movements of the bogie beneath' the carriage and on the other hand by'the springy movements of the carriageon the b0 ie.

The driving means including a turbine may comprise any steam engineand be located in any other place near the liquid receptacle. It has, however, proved most suitable to place the aggregate outside the end wallof the. condensing receptacle and the aggregate may also be situated on another or near the point of rotation.

, carriage coupled to the condenser carriage- In Fig. 2, designates the outlet of the turbine and 14 the end wall of the condensing receptacle forming a casing 16 surrounding the outlet 15. Near the ine AA the extension of which passes through the point of rotation mentioned above the steam conduit 15 is connected with the condensing,

thus increasing the tightness of the coupling; The packings may be tightened in usual manner by tightening the part 25.

In the modified embodiment of the coupling device between the outlet 15 and the condenser 14 or its casing 16, shown in Fig. 3, the outlet is provided in the proximity of line BB, the extension of which passes through the point of rotation mentioned above, with diaphragmsBO or is formed as such diaphragms, which owing to their elasticity may assume different positions thus allowing the mentioned movement of the outlet 15.

Several embodiments of the invention may be imagined without deviating from its principle, since movable packings of any kind may be used.

What we claim as new and desire to secure by Letters Patent of the United States of America is 1. In locomotives provided with condens ers and in which the power is transmitted from a steam engine to a wheel driving device by means of a toothed gearing, the

waste steam supplied to the condenser passing into a condensing receptacle, an arrangement characterized by the steam engine, the toothed gearing and the wheel driving device being located on a common bo ie, the

outlet of the steam engine being yie dingly connected to said condensing receptacle so as to compensate for all movements of the bogie relatively to said rece tacle.

2. An arrangement accor ing to claim 1 characterized by the steam outlet being substantially parallel to a plane through the driving wheel shafts.

' 3. An arrangement according to claim 1,

5. An arrangement according to claim 1 characterized by the steam engine being sit-- uated at the end wall of the condensing receptacle and having its outlet extending in the longitudinal direction of the condensing receptacle.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
